Application led May 27,

T0 all whom it may concern Be it known that I, HENRY N. HEILMAN, a citizen of the United States,'res'iding at St. Louis, State 'of Missouri, have invented a certain new `and useful 'lmprovementjin Coupon-Cutting Machines, of which the fol lowing is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the 'accompany- 'ing drawings, forminga part of this specification. I

' My invention relates to new and useful improvements in coupon cutting machines, the principal objects of my invention being to provide a relatively simple, practical device that is capable of vbeing easily operated for the purpose olf-cuttingwith a single stroke a plurality ofcoupons from sheets of bonds, Vor thel like, vand further to providea relatively simple machinehaving an adjustable blade carrying head which permits theangle of cut to be varied asdesired.

With the foregoing and other objects in view, my invention consists in certain new and novel features of construction and arrangement of parts hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Fig. 1 is an elevational view of a coupon cutting machine constructed in accordance Vwith my invention and with parts thereof in vertical section.

Fig. 2 is an enlarged vertical section taken approximately on the line 2-2 of` Fig. 1.

Fig. 3 is an enlarged horizontal section taken approximately on the line 3-3 of Fig. 1.

Fig. 4 is a perspective view ofthe blade utilized in my improved couponcutting machine.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates a base plate, preferably formed of metal, and in the forward portion of which is formed a recess ordepression 11 that is occupied by a removable block 12 of wood or analogous material which serves as the cutting table of the device. Formed integral with or fixed to the rear portion of base 10 is an upwardly and forwardly projecting bracket 13, and formed through the forward portion thereof is a vertically disposed opening 14 that servesas a bearing for a substantially i920. serial No. 384,778.

j cylindrical plunger 15, ,andv which Vlatter car; i ries lthe head and cutting'blade of the maj."

chine;` Froj ecting upwardly ffrom Vthe forward portion of bracket '13 tothe 'sides ofl-opento Y ing 14 are ears 16 between which is arranged the forward end of a'handflever'17, the

same being fulcrumed uponajrpin 18` which passes through the ears 16. The forward end of the lever is slotted vertically to form a pair of ears 19,1 and seated thereinto one side of the pivot pin 18 is a pin20 to which is pivotally' connected the upper end of a link 21 and the lowereend `vof the latter is pivotally connected in any suitable manner to the upper end of plunger15. v vInterpo'sed vbetween the underside'of hand lever 17 and the top of bracket 18 is a compression spring 22 that normallv maintains the hand lever Iat its upper limit of' movement and resists 75 its downwardy movement. The downward travel of the hand lever 17 is regulated vby an adjustable stop inthe form of' a screw 23 that is seated in the topI of arm' 13 to the y rear of spring 22.

Depending from the lower end of plunger 15 is a cylindrical stem 24C in the lower portion of which is formed an annular groove 25. Positioned on this stem 24is a collar 26 through the lower portion of which passes a pin or screw 27 the inner end of the latter being positioned in the groove 25. This pin retains the collar and parts carried thereby upon the stem 24' and permits said. collar to be rotated freely upon said stem.' Formed 90 integral with or fixed to the lowerend of collar 26is a. substantially .triangular block 28 that carries the cutting-blade and for the accommodation of the latter the lower portions of the side faces of said block that are disposed substantially 90 degrees apart are provided withgrooves 29 fwhich receive the. upper portionsY of the blade 30, and the latter being secured to block 28 by means of set screws 31 which pass through formed apertures in the lupper portion of the blade and engage in threaded apertures formed in said block.

As illustrated in Fig. el, the blade is formed i in one piece and with substantially one-half v105 of the body thereof disposed at right angles to the other half.l Further, in order to effect a movement of the cut coupons away fromfthe sheets to which they were originally attached, t-he beveled faces 32 which are 110 ,ir rra 'rr FCEi-*i suitably formed on the blade to produce the cuttingA edges' are disposed on the inner races or the two parts or the blade.

In order to lock the blade carrying vblock 28 to the stem 2% during the cutting 25 therein. These recesses 34 are preferably arranged 90 degrees apart thereby permittingv the blade carrying head to be adjusted so as to effect a cut at any corner of a sheet such as a coupon carrying bond.

n Under' normal conditions', spring 22 maintains hand lever 17 in its elevated position, and, consequently, the blade `carrying head is maintained at its upper limit of movement or in the position illustrated in Fig. 1. T he bonds from Which thercoupons are fto be cut are positioned on the block' 12 directly beneath the cutting head and the position of the latter and the blade carried thereby is adjusted by proper manipulation of screw 33 and which latterenga'ging in one of the r`ecesses 3a locks the blade carrying head in its adjusted position. n y

As hand leverv 17 is swung downward' link 21 will move plunger 15 downward through bearing 14 and, consequently, orcing the 'edge of the blade 30 through the sheets positioned on block 12 With the result that the coupons are cut along two edges, thereby separating the samerrom the bodies or the sheets or coupons, and at the same time moving the cut coupons? away from said sheets,v Which last action results from the arrangement of the beveled edges 32. Y

A* machine or my improved construction is comparatively simple, is capable of being cheaply produced, and provides ei'hcient means for rapidly cutting` coupons, or the like, vfrom sheets such as bonds.

l clainif a Y In a coupon cutting machine, a` base, a bracket projecting upvvardlyjtherefrom, a plunger' mounted for vertical sliding movement through said bracket, means for mov- 'said plunger downwardly, a block mounted for' rotation in a horizontal plane on the lower end of' the plunger, a blade removably carried by said bleek, which blade is provided With cutting7 edges disposed at right angles to'each other, the lo'Wer portion or' the plunger having four recesses disposed substantially QOYdegrees apart, and a' set-screw seated in the block adapted to be projected in to any' one of said recesses so as to loc'k the block in any one of four' predetermined positions and mealr'isY for holding the cutting block during the' time when the set screw' is loosened A In testimony whereof hhereunto affix my signature this 145th day `of May, 19,20`
